The optimal time for control pollinations was at cone stages 4 and 5 and optimal amount of pollen per pollination bag was – mL. Western white pine is a very good seed producer and can be easily managed in seed orchards to give very high seed production per cone and per by: 9.

Abstract. Natural variation in seed characteristics of eastern white pine (Pinus strobus L.) trees and its relationship with the size, form, and crown class of parent trees was examined in second-growth, white pine mixedwood stands in were collected prior to and following partial harvesting of two stands during 2 years of above-average seed production.
Distribution: Western White Pine is native to southern British Columbia, western Washington, northern Idaho, western Montana, the Cascade Mountains of Oregon and the Sierras of California. Growth: They are fast growing when young and may grow 1½-2 feet (cm) in a year. In cultivation, they sometimes reach feet (40m). The largest, growing in Oregon, near Fish Lake east of Medford, is. Cooperative have established additional seed orchards, but most are not yet producing seed, and cone and seed insects in the three producing orchards are seriously reducing yields. Furthermore, as the orchard yields decrease, the demand for western white pine planting stock is increasing (table 1). So, western white pine seed. problem. Seed orchards should be mowed to minimize competition from other plants. Tillage between plants and rows will enhance growth and seed production, but a conservation plan should be developed to address the orchard site’s erosion potential. Discing on the contour between rows may be a viable alternative to tilling the entire orchard. Get the most up-to-date information on growing tree fruit on a commercial scale.
